In sports broadcasting, a sports commentator (also known as sports announcer, sportscaster or play-by-play announcer) gives a running commentary of a game or event in real time, usually during a live broadcast, traditionally delivered in the historical present tense. Radio was the first medium for sports broadcasts, and radio commentators must describe all aspects of the action to listeners who cannot see it for themselves. In the case of televised sports coverage, commentators are usually presented as a voiceover, with images of the contest shown on viewers' screens and sounds of the action and spectators heard in the background. Television commentators are rarely shown on screen during an event, though some networks choose to feature their announcers on camera either before or after the contest or briefly during breaks in the action.

The main commentator, also called the play-by-play announcer or commentator in North America, blow-by-blow in combat sports coverage or lap-by-lap for motorsports coverage, is the primary speaker on the broadcast. Broadcasters in this role are valued for their articulateness and for their ability to describe each play or event of an often fast-moving sporting event. The ideal play-by-play voice has a vocal timbre that is tolerable to hear over the multiple hours of a sports broadcast and yet dynamic enough to convey and enhance the importance of the in-game activity. Because of their skills, some commentators like Al Michaels in the U.S., David Coleman in the UK and Bruce McAvaney in Australia, may have careers in which they call several different sports at one time or another. Other main commentators may, however, only call one sport (Mike Emrick, for example, is known almost exclusively as an ice hockey broadcaster). The vast majority of play-by-play announcers are male; female play-by-play announcers have not seen sustained employment until the 21st century.

Radio and television play-by-play techniques involve slightly different approaches; radio broadcasts typically require the play-by-play host to say more to verbally convey the on-field activity that cannot be seen by the radio audience. It is unusual to have radio and television broadcasts share the same play-by-play commentator for the same event, except in cases of low production budgets or when a broadcaster is particularly renowned (Rick Jeanneret's hockey telecasts, for example, have been simulcast on radio and television since the late 1990s).

The analyst or color commentator provides expert analysis and background information, such as statistics, strategy on the teams and athletes, and occasionally anecdotes or light humor. They are usually former athletes or coaches in their respective sports, although there are some exceptions.

The term "color" refers to levity and insight provided by analyst. The most common format for a sports broadcast is to have an analyst/color commentator work alongside the main/play-by-play announcer.[1][2][3] An example is NBC Sunday Night Football in the United States, which is called by color commentator Cris Collinsworth, a former American football receiver, and play-by-play commentator Al Michaels, a professional announcer. In the United Kingdom, however, there is a much less distinct division between play-by-play and color commentary, although two-man commentary teams usually feature an enthusiast with formal journalistic training but little or no competitive experience leading the commentary, and an expert former (or current) competitor following up with analysis or summary. There are however exceptions to this — most of the United Kingdom's leading cricket and snooker commentators are former professionals in their sports, while the former Formula One racing commentator Murray Walker had no formal journalistic training and only limited racing experience of his own. In the United States, George "Pat" Summerall, a former professional kicker, spent most of his broadcasting career as a play-by-play announcer.

Although the combination of a play-by-play announcer and a color commentator is standard as of 2014[update], in the past it was much more common for a broadcast to have no analysts and just have a single play-by-play announcer to work alone. Vin Scully, longtime announcer for the Brooklyn/Los Angeles Dodgers baseball team, was one of the few examples of this practice lasting into the 21st century until he retired in 2016.

A sideline reporter assists a sports broadcasting crew with sideline coverage of the playing field or court. The sideline reporter typically makes live updates on injuries and breaking news or conducts player interviews while players are on the field or court because the play-by-play broadcaster and color commentator must remain in their broadcast booth. Sideline reporters are often granted inside information about an important update, such as injury, because they have the credentials necessary to do so. In cases of big events, teams consisting of many sideline reporters are placed strategically so that the main commentator has many sources to turn to (for example some sideline reporters could be stationed in the dressing room area while others could be between the respective team benches). In motorsports, it is typical for there to be multiple pit reporters, covering the event from along pit road. Their responsibilities will include covering breaking news trackside, interviewing crew chiefs and other team leaders about strategy, and commentating on pit stops from along the pit wall.

In British sports broadcasting, the presenter of a sports broadcast is usually distinct from the commentator, and often based in a remote broadcasttelevision studio away from the sports venue. In North America, the on-air personality based in the studio is called the studio host. During their shows, the presenter/studio host may be joined by additional analysts or pundits, especially when showing highlights of various other matches.

Various sports may have different commentator roles to cover situations unique to that sport. American football, for example, regularly employs rules analysts in its broadcasts; usually a former referee, a rules analyst explains penalties and controversial calls and dissects instant replay reviews to predict whether a call will or will not be overturned.

In video games, and particularly eSports, commentators are often called shoutcasters; this term is derived from the free plugin for Winamp called SHOUTcast, which enabled users to live-stream audio-only feeds across the Internet.[4]

While sports broadcasts took place from 1912, Florent Gibson of the Pittsburgh Star newspaper broadcast the first sports commentary in April 1921, covering the fight between Johnny Ray and Johnny "Hutch" Dundee at the Motor Square Garden, Pittsburgh.[5]

In 1975, the National Hockey League (NHL) made headlines when two coaches from the NHL All-Star Game in Montreal allowed Robin Herman and Marcel St. Cyr. access into the men's locker room. Both were believed to have been the first women ever allowed to enter a professional men's locker room to conduct a post-game interview.[6] Sport organizations began to follow in the NHL's footsteps and allowed for other female sportswriters to be given the same access as men sportswriters.[7]

It was not until the year 1977 when Melissa Ludtke, a sportswriter from Sports Illustrated, was given the assignment to cover the New York Yankees playoff series but was denied entry into the men's locker room. Baseball commissionerBowie Kuhn and other officials chose to discriminate against her based on her sex. Knowing that this would put Sports Illustrated in a disadvantage from other publishers, Time Inc. and Ludtke filed a lawsuit against Kuhn.[7]

After the access of allowing women in was put into effect, the Yankees organization allowed reporters to spend ten minutes interviewing players and was then asked to leave and wait. Male reporters were unhappy with this and blamed the women from keeping them out and not being able to do their job. For some men they finally understood what women reporters had been dealing with.[8]

In 1990, the issue made its way back into the headlines when Lisa Olson made a public statement revealing that players from the New England Patriots had exposed themselves while interviews were being conducted. This prompted other female reporters who had been harassed to come forward. Accusations were made that women appeared as being "too friendly" while performing interviews or conversing too long with players as though they were flirting. Their credibility became undermined. Thus, the issue of sexism was still present, despite the equal access to men's locker rooms.[7]

Though not always the case, in professional wrestling, the color commentator is usually a "heel sympathizer" (or a supporter of the "bad guys") as opposed to the play-by-play announcer, who is more or less the "voice of the fans" as well as supporters of the "good guys" (or babyfaces). Though both are supposed to show neutral stance while announcing, the color commentators (especially when they support heels) are usually more blatant about their stance than the play-by-play announcers. Jesse "The Body" Ventura and Bobby "The Brain" Heenan pioneered the "heel sympathizer" for color commentary in wrestling. Jerry "The King" Lawler later made a successful transition into the role, though Lawler has since shown more sympathy for faces (partially due to being over with fans after nearly forty years in wrestling). In some cases, commentators are also active managers for wrestlers, usually following continuity as heels. Former Extreme Championship Wrestling color commentator Cyrus was known for having dual roles as a heel manager and a somewhat neutral commentator. Acting as a commentator has also been used to keep injured wrestlers in the public eye while recuperating. Special guest color commentators serve a two purposes: the primary is usually to place them in position to interfere with the match they are calling, the second is to provide promoters with the opportunity to determine if this performer can speak well extemproraneously.
